I'm interested in playing MH: World as someone who has put countless hours into the MH series but it's fundamentally a different game from MHXX. That's why fans like me want MHXX to be localized alongside MH:World. For example:
MHXX has Hunting Styles (Adds Brave Style and Alchemy Style)
MHXX has Hunter Arts (Super Moves that you fill up a meter to use)
MHXX has Prowlers (Cats) as playble characters
A freaking flagship rocket dragon + super boss versions of iconic monsters from the series that are called "Deviants"
MH: Worlds has none of this and is looking like a more grounded take on the monster hunter concept that doubles down on tracking and stealth which are elements which took a backseat to the more action focus of later games. Then there's the fact that it's not on a portable console and lacks local co-op. It would be truly sad if capcom stopped releasing MH games with the classic formula in the west and ignored the players like myself that still wants this style of game because they sure as hell aren't going to stop making portable entries for the Japanese audience. I think that both World and Portable entries can exist in the same marketplace in the west.
